  • receiving and storing, by the transaction backup server, an input message;

    receiving, by the transaction backup server, a notification from the transaction processing server having completed a transaction of a message, the notification including a message digest and a message identifier (message ID) associated with the message;

    comparing, by the transaction backup server, the message ID in the notification received and a stored message ID obtained from the input message that was previously received and stored by the transaction backup server;

    comparing, by the transaction backup server in response to a match of the message ID, the message digest in the notification received and a stored message digest obtained from the input message that was previously received and stored by the transaction backup server; and

    storing, by the transaction backup server in response to a match of the message digest, the stored input message directly in a physical storage.
